STEAM-BOILER.

' To all whom it may concern:

middle row of tubes 1 is indicated Be it. knownthat I, EGBER' R. Morrison,

a citizeu' of the United States, residing at- Sharon, 1n the county of Mercer and State of Pennsylvania, have invented certain new and useful Improvements in Steam-Boilers,

In consequence ofthis arrangement it will, .be seen that any tube of the' row 9 may be ,taken out or replaced through-the wide] I spaces 11 in the corresponding outerurow, I and furthermore-any one of the tubes 8 be taken out or put in. through said space, one tube 8 being removable through the space at one side and thenext' tube being re- Y movable through the space at the opposite of which the following is a-specification. This invent-ion relates to'water tube boilers, andembodies a new arrangement of the tubes in such boilers having a plurality of rows of vertical tubes connected at top and bottom to upper and lower headers.

Five rows of tubes are used, and 'the tubes in thetwo outerv rows are grouped in pairs, the pairs one outer row alternating or being staggered with respect to the pairs in the other outer row, and the tubes of the hon-applied to three pass boilers of the don )assa e or s ace for the removal .of an of the tubes in the inner rows whereby any tube in the boiler may be removed'without necessitating the removal of other tubes.

. A further, feature of the invention is the location of tubes, in multiple section boilers,

in such. mannerthat all "the tubes are sub stantially equidistant, so there is no'l arge alley for the heat to follow. The invention is illustrated in the accompanying drawings in which Figure 1 is'a vertical long'itudinal section of a single section boiler with the tubes ar-' ranged as stated. Fig. is a vertical cross section. Fig. 3 is a section on the line of Fig. 2. Fig: 4 is a section on the line 4+4:

of Fig. 2. Fig. 5 is a vertical section, and Fig.- 6 is a horizontal section, of a double section. boiler embodying. the invention.

' Referring specifically to the drawings, the lower headers are indicated at' 6 and the upper headers at 7 and these headers are connected by'vertica-l water tubes in banks, thetubes being arranged in five rows. The

Eachtube-Q is located opposite to tubes of the row 8, with a sufiicient distance apart to allow each tube -8'to passbetween the tubes 9, and the said tubes, 9are opposite each other on the respective sides. The; tubes 10 of the outer rows are arranged in pairs, with a comparativelywide space, indicated at 11, between eachpair,this space being preferablyin exactliue with the space at 8, and

What I claim is:

1,. A tubular boiler having five rows of tubes, located beside each other, the tubes of the two outer rows being located with hlternate wlde and narrow spaces between the tubes. of each of said rows, the wide spaces in each of said row s'being oppositethe narrow spaces in the other.

2. A tubular boiler having five tubes located beside each other, the distance between the three inner rows being less than the distance between "adjacent tubes. in any one of said rows, and the tubes of the twoogiier' rows being located in pairs with wide s ces' between each pair, the wide spaces bdinglocated alternately in the two opposite outer ws. 3. A tugilar boilerhaving five rows of tubes, located beside each other, the middlerowbeing-staggere'd with respect-to. the

' two adjacent rows and the tubes of the two outer rows being located with alternate wide andynarrow spaces between the tubes of eachof said outer rows, the wide spaces in each of said rows being opposite the nar" row spaces in the other and in linewith the tubes in, theimiddlerow and the arrangement of these wide and narrow spaces and the distance apart of the outer and adjacent rows being such as to allow a passage for the reniovalof anytu'be 9, in the inner rows as well asza passage for the remove of any tube 8, inthe-middle row; i v 4. A tubular boiler having-five rows of tubes located beside each othenthe middlerows of.

row being staggered with" respect to the two dj cent roWS and the distancebetween the three inner rows being less than the distance between adgiacent tubes in any one' of said rows,'- and t etubes. of the two outer located alternately in. the two opposite outer jrowsbeing located in pairswith wide spaces a between each pair, the Wide spaces being as to allow'a passage for the removal of any 7 c tube 9, in the inner rows, as well as a pas-. 'sa' e forthe removal of any tube 8, in the "mlddle row. a Y

5'. water tube" boiler having a heating chamber through which the combustion products flow from front to rear, multiple drums located side side in said chamber and extending lengthwise from front to rear therein, in the same general direction as that of the flow of products through said chamber, banks of tubes connected to said drums and standing beside each other in said chamber, the banks beingarranged in relation to, the side walls of the heating between the outside tube of one bank and the outside tube of another bank, is pract1- cally the same as the'space between any two tubes of. any one, bank, the tubes of the banks being bent in such a manner that this spacing,will exist throughout the larger part of the tub length, thus resultin 1n securing a uniformity in size of all the eat alleys between; all the rows of tubes-regardless as to whether the'heat alleys are; formed by two tube rows of the same bank, two tube rows .of diflerent banks ,or a tube row chamber-and'in relation to adjacent banks 'in such manner that the space between theoiitside tube of one bank and the wall, or

on one side and the side wall of the heating chamber 011 theother' side.

6.'A tubular boiler having fiv e rows of tubes located beside each otherythe tubes of the three inner rows being staggered with respect to each other and the'tubes of the two outer rows being located-to form space in each of said "rows being opposite the narrow space in the other, and 'a bent bafile wall extending across the rows and .located at each. side of the bank in what would otherwise be oneof the narrow spaces in the'twp outer rows.
